CONTAINER AND METHOD SEALING.

Application filed September 9, 1922. Serial No. 587,151. i

The object of this invention is to provide a novel container and methodof sealing.

Inthe attached drawings: Figure 1, is a front view of a container madein accordance with my nvention;

Fig. 2, is a section on the line 2-2, F1g. 1; Fig. 3, is aback view ofthe container 11- lustrated in Figs. 1 and 2;

Fig. 4, is a front view-of the container 1 sealed; I

Fig. 5, is a section on the line 5-5, Fig. 4. Fig. 6, is a fragmentaryenlargement of the upper portion of the. sealed bag as 11- lustrated inFig. 5, and

15 Fig. 7, is a view in perspective of a container illustrating amodification within the scope of the invention.

In the industry, bags are distinguished from envelopes chiefly by themethods of manufacture, and by the fact that whereas in the envelope thesealing flap is on the front face, in the bag this flap (when provided)is on the rear face.v In sealing a bag in normal fashion, it accordinglis necessary to turn the flap down over t e front face, which mars theappearance of the container.

I have found, however, that a bag of the usual form lends itself to thedevelopment of a container which is particularly useful for second-classmail where it is necessary to leave the container sufliciently open topermit inspection of the contents.

With reference to the drawings, I have in Figs. 1 to 6, inclusive,illustrated a common form of bag, this bag, as will be seen, consistingof a tubular blank'l of paper turned back at the bottom and sealed asindicated at 2, the rear side of the blank at the top extend- 40 ingsomewhat-above the front face to form a flap At the rear of the flap 3,I prefer to place an adhesive 4, such as is commonly used on the edgesof envelopes, and it is" also preferable to score the bag near the top,

as indicated by the reference numeral '5,

' thereby to assist the folding back of the upr portion of the bag andinsuring its lying flat when folded.- The bag so formed and secured asillustrated in Figs. 4 and 5 by turning back the upper portion of thebag along the scored line 5 and securing the flap 3 to the back of thebag by means of the adhesive 4, may beemployed for sending second orthird-class matte-rs through the mails, this by reason of the fact thatthe turned-back portion 6 of the front face of the bag is held looselyin place only by its connection with the flap 3, and the bag may bedistorted to permit passage of the hand under the flap and into theinterior of the bag, or to permit inspection of the contents. Althoughth1s invention finds its most useful application in the case of the so-7 called bags, it will be understood that it is not limited to thisparticular form of container. Thus, for example, as shown in Fig. 7, theflap 3 is eliminated, the front and rear faces of the container being ofequal height, and the strip of adhesive 4 is secured to the upper edgeof the rear face of the bag, so that when the upper portion of the bagis turned, back, this adhesive may act to effectively seal the containerwhile still permitting. access to the interior without breaking theseal.

Still other modifications are possible with no departure from theessential features of the invention.

I claim:

1. A bag comprising a tubular blank sealed at one end and having oneface extending at the other end beyond the end edgeof the other face,and an adhesive on the outside and at the open end of said bagconstituting'securing means when the aforesaid open end is folded overto close the bag.

2. A bag comprising a tubular blank sealed at one end and having itsrear face extending at the other and normally open end beyond the endedge of the front face, and an adhesive on the outside of the extensionof said rear face constituting securing means when the said open end'isfolded over to close the bag.
